TALLAHASSEE, Fla. (AP) — Florida's candidates for governor openly sparred over guns on Monday after a mass shooting at a video game tournament.

Democrats contended Republicans were ignoring a wave of gun violence in the state, including the February shooting at a high school in Parkland that left 17 people dead, and the massacre at a gay nightclub in 2016 that left 49 people dead. The two GOP candidates lashed back that Democrats were attempting to politicize a tragedy.

Authorities say 24-year-old David Katz of Baltimore killed two people and wounded 10 others before fatally shooting himself Sunday at a Madden tournament being held at a riverfront mall in Jacksonville.

U.S. Rep. Ron DeSantis and Agriculture Commissioner Adam Putnam, both Republicans, scrapped plans to hold campaign events in the northeast Florida city after the shooting. But four of the main Democratic candidates visited Jacksonville and called for stricter gun-control laws and reducing the clout of gun-rights organizations such as the National Rifle Association.

Democrat Gwen Graham called out DeSantis and Putnam for canceling their planned campaign events.

"The fact that they were afraid to come and answer questions says all that needs to be said," said Graham.

A shooting across the street from Auburn University's campus early Sunday killed one person and wounded four others, three of them teens, in an incident that does not appear random, police in the southeast Alabama city said.

The shooting happened hours after students had celebrated a win over Alabama State's football team Saturday evening.Auburn city police received a report of gunfire about 2:24 a.m. (3:24 a.m. ET) on West Magnolia Avenue, a popular thoroughfare featuring bars and restaurants and forming the northern border of campus, which is home to about 30,000 students.

Officers "were already in the immediate vicinity of the call dispersing a large crowd," according to a police news release.The university's emergency alert system sent a tweet at around 4 a.m. informing students that there had been a shooting and warning them to stay away from the area.

A man killed his wife and four other people in shootings across three locations Wednesday evening near Bakersfield, California, before killing himself as a sheriff's deputy confronted him, authorities said.

The crime spree took roughly 15 minutes, and investigators are trying to figure out why the man went on the rampage, Kern County Sheriff Donny Youngblood said."I'm certainly speculating right now ... but I'm pretty comfortable that there will be a connection between all these players," Youngblood said at a news conference late Wednesday.

A gunman killed three people and wounded two others Thursday at a drugstore distribution center in Harford County, Maryland, officials said Thursday.

The shooting occurred at a Rite Aid support facility, and "what I understand is the location is secure," said Rite Aid spokeswoman Susan Henderson. Roughly 1,000 employees work there, she said.

"The distribution center is where products are received and processed for delivery," she said. "This is part of a large facility that is a distribution center. The shooting happened adjacent to the primary building."
